EXCELSIOR-MACHINE.

SPECIFICATION forming part of Letters Patent No. 766,050, dated July 26,1904.

T0 a/ZZ 2071.077?, t may concern.-

Be it known that I, GEORGE P. LYON, a citizen of the United States,residing at Voodford, in the county of Caroline and State of Virginia,have invented certain new and useful Improvements in Excelsior-Machines,of which the following is a specification.

This invention relates to machines for shredding wood in the'manufaotureof eXcelsor, the purpose being to devise a machine of novel structurewhich will be light running, capable of a greater output when comparedwith like machines of given size operating a like interval of time andutilizing a corresponding number of units of force, and which will bedurable, eiiicient, and discharge the excelsior at one point.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- Figurel is a top plan view of a machine embodying the invention. Fig. 2 is aside view thereof. Fig. 3 is a detail perspective view of a portion ofthe rim of the cutterwheel, a support for the bolt or block, thepressure-lever, and adjunctive parts. Fig. 4 is a cross-section on thelineX X of Fig. l, showing the parts on a larger scale. Fig. 5

l is a detail perspective view of the carrier and clearer. Fig. 6 is adetail perspective view of a portion of the cutter-wheel, showing theblock and the cutter supported thereby.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

rIhe cutter-wheel is indicated at l and is arranged in the usual mannerto revolve in a horizontal plane about a vertical axis and is providedwith a series of scoring and cutting blades, which may be of anystructural type common in machines of this class.

Application filed February 6,. 1904. Serial No. 192,362. (No model Thescoring-knives are indicated at 2, and the cutting knives or blades at3, both sets of knives being applied to blocks 4, which are fitted inopenings arranged at intervals in the circumferential portion of thewheel. The power for driving the cutter-wheel is applied preferably tothe outer portion, thereby obviating the strain upon the shaft andspokes or arms common in'eXcelsior-machines as generally constructed andoperated. Within the purview of the invention the power may be appliedto the wheel in any determinate way, and, as indicated,the rim 5 isprovided with a groove in which a cable 6 is fitted and is connectedwith any suitable source of power for transmitting motion to thecutter-wheel. The rim of the wheel is hollow, as shown at 7, andcomprises inclosing walls 8, 9, and l0. The walls 8 and l() areright-angularly disposed and are connected with the wheel so as torotate therewith, whereas the wall 9 is stationary and is supported inany substantial way, as by means of the pillow-blocks l1, upon which aremounted the standards l2, to which the plates 13, receiving the bolts orwooden blocks, are attached. The walls 8 and 9 are transversely spaced,and the wall l0 constitutes a bottom and closes the lower end of thespace 7, constituting the hollow rim or conveyer into which the shredsof wood or eX- celsior are discharged. A bracket 14 extends lfrom thewall 9 opposite to each of the standards l2 and in conjunction with saidwall supports a roller 15, upon which the wheel is mounted for rotation.The rollers or wheels l5 are preferably located in the plane of the rim5, whereby the best results are attained as regards stability ofstructure and eiiciericy.

The wall or support l0 constitutes, in effeet, a carrier, since theexcelsior drops thereon and is supported thereby and carried to thedeterminate point of discharge. The vertical walls 8 and 9 preventlateral displacement of the excelsior, and the wall 8 further serves asa connecting means between the part 10 and the wheel. By having theouter wall 9 stationary it is admirably adapted for supporting thewheels l5, which carry and sustain the weight of the cutter-wheel, andalso provides means for carrying the clearer IOO 16, by means of whichthe excelsior is removed from the carrier and directed into a chute 1Tor other receptacle arranged for recept-ion of the material. The clearer16 may be a part of the wall 9 or may be attached thereto. rl`he clearer16 consists of a plate extended across the space 7 and sweeping over thehorizontal wall 10 and inclined to the plane of motion of thecutter-wheel, so as to direct the excelsior outward through the opening'18, formed in the outer wall 9 and constituting the discharge.

Each of the horizontal plates 13 is provided with an opening directlyabove the rim of the cutter-wheel, said opening being reinforced by avertical rim 19, which forms, in effect, a hopper or guide to receivethe bolt or block 20, which is shredded in the operation of the machineto provide the excelsior. A lever 21 is pivoted to each of the plates 13and normally exerts a pressure on the bolt or block 20 to advance thesame to the cutting mechanism as the excelsior is formed.

By applyingl the power to the outer portion of the cutter-wheel the huband spokes of the wheel may be compartively light, since they are notsubjected to the strain which would be required if utilized fortransference of the power to the rim carrying the cutting mechanism.Moreover, a minimum amount of energy is required to be expended foroperating the machine, and a greater number of bolts or blocks 2O may beplaced in position for formation of the excelsior. By having thematerial collect-ed from all of the bolts or blocks and discharged at acommon point the space beneath and around the machine is kept clear, thematerial prevented from Contact with the grease or moving parts of themachine, and the annoyance and expense of collecting and gathering thematerial whollyobviated.

The horizontal plate 10 acts in the capacity of a supporting-surfaceupon which the material is received and carried in a loose state untilswept laterally therefrom by the clearer 16. lnasmuch as the cutters arearranged closely about the peripheral portion of the cutter-wheel 1, thematerial is practically distributed uniformly and loosely upon thesupporting surface or wall 10 and is moved laterally therefrom atapproximately the point l of its reception, thereby preventing thepushing of the material ahead and the rolling and entanglement thereof,as is the case where the material drops from the cutter-wheel upon astationary supporting-surface and is moved thereover by means of anexpelling device traveling with the cutter-wheel, with the result thatthe material is bunched, crowded, and condensed. In accordance with thisinvention there is, in effect, a continuous discharge of the material ina loose state.

Having thus described the invention, what is claimed as new is- 1. In anexcelsior-machine, the combination with the wheel horizontally arrangedand provided with a series of scoring and cutting knives, a wallarranged below said wheel and connected for rotation therewith andadapted to receive and carry the excelsior, and a stationary clearerextended across said wall to sweep the excelsior laterally therefrom atapproximately the point of its reception thereon, substantially asdescribed.
